DEVICE FOR WITHDRAWING TEMPLETS IN THE MANUFACTURE OF CURBSTONES, 8L0.

SPECIFICATION forming part of Letters Patent No. 792,830, dated June 20, 1905. Application filed June 27, 1964. Serial No. 214,315.

To all whom it may concern.-

Be it known that I, ALBERT H. KENNEDY, a citizen of the United States, residing at Rockport, in the county of Spencer and State of Indiana, have invented a new and useful Device for ithdrawing Templets in the Manufacture of Gurbstones, &c., of which the following is a specification.

This invention relates to the manufacture of cement or artificial-stone curbs, gutters, and the like, the objects of the invention being to provide a positive mechanical means for evenly and vertically withdrawing the templets from between the sections and for simultaneously preserving the adjacent edges of the cement sections from crumbling or being otherwise marred by reason of and during such withdrawing of the templets.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a vertical transverse sectional view taken between two adjacent sections of a combined artificial-stone or cement curb and gutter, a device constructed in accordance with my invention bein g shown in position thereon and in the act of and partially withdrawing a templet. Fig. 2 is a detail in elevation of one of the forms hereinafter referred to; and Fig. 3 is a front elevation of the combined gutter and curb, my device being applied thereto and in position for withdrawing the templet.

Similar numerals of reference indicate similar parts throughout thedrawings.

Although I have herein illustrated my invention in connection with an artificial-stone or cement combined gutter and curb, yet I would have it understood that such is merely for the purpose of exemplification and that the invention is not at all limited to this application; also, that the mechanical means employed may be varied at will for the purpose of securing the ultimate result.

The invention comprises a pair of opposite spaced-apart forms or sections 1 1, the under sides of which, as will be obvious, vary in shape to conform to the contour of the object upon which they are mounted. In this instance, being designed for use in the manufacture of artificial-stone or cement combined curbstone and gutter, said forms are similarly cut away at their rear under sides, as at 2, so as to conform to the same.' These forms are each provided with a half-cylindrical centrally-located vertical recess 3, which extends from the upper to near the lower end of the form, the two recesses being in register or transversely opposite. The forms may be connected at suitable points by any desired means, whereby they are maintained in proper relation; but I prefer to employ a flanged threaded nut or socket 4:, the same having its upper flanged end bolted to the upper ends of the forms and its central threaded hub portion extending down into the semicylindrical recesses 3.

Threaded in the nut 4, so as to be vertically adjustable therein, is a vertical screw 7 which near its upper end is swiveled in an eye 6, formed at the center of a transverse bar 5.

Above the bar 5 a cranked handle 8 is made fast upon the shaft 7 and through it the shaft may be rotated so as to be fed vertically up or down in the nut 4c and in so doing raise and lower the bar 5. From the ends of the bar depend links 9, the same being loosely pivoted, as at 10, to the extremities of the bar 5. The lower ends of these links may terminate in hooks 11 or be provided with any other desired means for engaging with the opposite ends of a templet.

14 designates a combined curb and gutter, such as is now usually formed in sections and of cement.

12 designates the usual form of partitionplate or templet, which conforms to the object being molded in this instance the combined curb and gutter-and has, as is usual, its extremities reduced and extended to form engaging arms 13.

15 and 16 are the usual mold-boards.

It is the present practice in the manufacture of artificial-stone and cement objects such, for instance, as curbs and gutters to mold the same, locating between each section a thin removable templet or partition, which of course must be withdrawn at a suitable time or step in the operation. This Withdrawal has been accomplished with more or less ditficulty by hand, the result being that the adjacent sections of the objects slightlyv adhering to the templet portions of said sections will be broken off or removed with the templet, thus causing a marring of the edges of the cement objects and preventing the formation or preservation of the desired sharp edges. By my invention, however, the templets are removed gradually, steadily, and vertically by a positive mechanical means, and during such operation the forms or sec tions 1 1, resting upon the opposite adjacent edges of the cement objects, hold said edges against any tendency to disintegrate.

After the combined gutter and curb or other object has been molded and when it is desired to withdraw the'templet the forms or sections 1 1 are placed in position, so that each form is flush, or substantially so, with the end of a section of curbing. The links are lowered by a manipulation of the crarik 8 and their lower hook ends engaged with the extensions 13 of the templet, as shown in Fig. 3. It now simply remains to operate the crank so as to feed the screw upward, whereby, as shown in Fig. 1, the templet 12 is gradually, positively, and uniformly elevated from between the cement sections, while at the same time the forms or sections 1 1 press firmly upon the cement sections at opposite sides of the templet.

Of course the sections 1 1 may be made of any suitable material and solid or otherwise, the object being to make them of suflicient weight to cause them to retain their positions and exert sufficient pressure upon the cement objects.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, in a device for the purpose described, of opposite forms spaced apart and adapted to receive a templet therebetween, and mechanism mounted on the forms and adapted to be raised and lowered and embodying templet-engaging devices.

2. The combination, in a device for the purpose described, of opposite forms spaced apart connected and adapted to receive a'templet therebetween, and mechanism mounted on the forms and adapted to be raised and lowered and embodying templet-engaging means.

3. The combination, in a device for the purpose described, of opposite forms spaced apart and connected together andpro'vided with corresponding vertical recesses, a nut located in the upper ends of the latter, a threaded crankshaft located in the nut, a cross-bar swiveled on the crank-shaft, and links suspended from the ends of the cross-bar and terminating in hooks adapted to engage the extensions of a templet.

4:. The combination, in a device for the purpose described, of opposite forms, a raising and lowering device adapted to engage the extensions of a templet, and means arranged upon the forms for operating said raising and lowering device.

5. The combination, in a device for the purposes described, of a support, a crank-shaft threaded therein, a cross-bar swiveled on the crank-shaft, a templet, and templet-engaging means depending from said cross-bar.

6. The combination, in a device for the purposes described, of a support adapted to surmount the molds and conforming on its under side to the adjacent side of the objects within the molds, said support having an intermediate templet-reeeiving recess, raising and lowering means carried by the support, and templetengaging devices carried by said means.

7. The combination with adjacent molds, and an intermediate templet, of a support thereabove having a space to receive the templet, and means carried by the support and adapted to be raised and lowered and for removable connection with the templet.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT I-I. KENNEDY.
